Why on earth would you take a picture that's OOF, note in your post that it's OOF, but still try to draw a conclusion from that?
We all miss shots. That's completely fine. But don't post a missed shot and try to pass it off as a lens performance issue. State it as it is - a skill issue, a lack of caring, or an actual mechanical failure (if you can prove it).
All you had to do was either omit the failed picture from testing - or just spend the extra 3 seconds to get it in focus. Not that hard lol.
I will type real slow and load so maybe you can understand. I shot 322 images with the 600mm/1.4X TC. In every single case I did not release the shutter until I had an AI confirmed locked green little box on that eye that the "bird mode AI subject recognition" provides on the a1 II. It is exactly the same process used for the 300mm GM with 2X TC and the 400-800. In the case of the 123 images shot with the 300GM and the 157 images shot with the 400-800, NONE of them were out of focus. Zero, None Zilch!!! With the 600mm/1.4X, some are slightly better and some slightly worse but none compare to the other sharpness of the other two lenses. I didn't cherry pick a bad sample. If I excluded the less sharp images I would have no images left from the 322. That isn't a test method problem. It is either a bad copy (most likely) or a bad design(less likely). I won't know which unit I get a new copy. Can this lens take a picture with OK sharpness? Yes I have posted one below. Would it have been sharper with either of my other two lenses? Well yes it would and that is the problem.
Now please GO AWAY
